SOFA-BED.

Specification of Letters Patent.

Patented Mar.' 2l, 1911.

To all whom 'it may concern: l

Be it known that I, SoLoMoN Kuren', a citizen of the United States,residing at Chicago, in the county ofCoolf and State of 1llinois',-haveinvented a new anduseful Improvement in Sofadeds, of which the followingis a specification.

invention relates particularly to combination sofas and beds, in whieh afoldable mattress-frame is normally housed Within the main frame beneaththe seat of the sofa vand equipped with afoldable bed-bottom,

tion is provide a simple construction ofY or wire mattress the partsbeing so related as to afford room between the sections of t-he'fol'dedbed for' the bedding, z'. e., the mattress proper, bed-1inen 'andcovers.

The primary object of the present inven- 'oombined sofa and bed whichmay be comortubly employed either as a sofa or a bed,

sind which can be manufactured at very to be' unfolded in theoperation-of swinging the seat to the inverted'. position. In thisconstruction, there is employed a truss which isA pivotally supported atthe lower' front portion ofthe end-standards' of the frame; and thefolded bed comprises a central bedsection which is pivotally mountedupon the -arms of said truss, and substantially U- shaped front and rearbed-sections pvotally connected with the intermediate bed-section.

The seat hasits front portion connected with thel frame by aV sort ofdouble-hinge arrangement, which permits the seat to be swung to aposition in front of the frame, and the front bed-section is attached tothe 4seat so that the bed will be unfolded when the seatisV swung to theinverted position. The rea-r portion ofthe rear bed-section is mountedupon links, or folding legs, whose lower ends are connected with guideswhich permit thefolding to take place.

ln the. accompanying drawings-Figure 1 tfeprcsents a sectional view ofmy improved combined sofa and bed in the open position; Fig. 2, a'broken perspectiveview lllustrat- I ing the manner in which the trussemployed is plvotally connected -with the' main frame; Fig. 3, a brokensectional view similar to the section shown in Fig. 1, but showing thestructure in sofa form; and Fig-4, a broken horizontal sectional viewshowing the strucf. .ture in bed form.

In the preferred construction, A represents a main frame; B, a pivotallysupported back C, a seat mounted on the main fra-me and. adapted toswing to a position in front of the main frame; D, a foldablemattress-frame, o1 bed-frame, normally housed within the main frame infolded condition beneath the seat .of the sofa, as shown in Fig. 3, E, atruss pivotally mounted on the main frame, upon which the folding bed ismounted and F, links, or folding legs, connected with the rearportion ofthe rear bed# section.

The frame A may be of any suitable construction. In the constructionillustrated, it comprises end-standards 1' which may be of Wood andasornamental as desired; and a. rear connecting member 2 'joining saidend-standards.

The back B may be of any approved .construetion. As shown, it isequipped at the upper portion of its ends with pivotal studs 2l whichare received in pivot-sockets (not shown) with which the upper rearportions of the arms, or end-standards, l of the sofa are provided. Theback stands normally in the rearwardl -inclining posit-ion shown inFig..3, but w en disengaged from the seat of the sofa, the back dropsautomatically to the vertically depending position shown in Fig'. 1, soas not to interfere with the use of the bed. I

The seat C may be of any suitable con struction. It preferably comprisesthe-usual frame.. springs mounted thereon, and a cushion-'pad mounted onsaid springs. It has pivotally connected with its ends links 4, which,in turn, are joined byl-pivots 5 to links. The linkpf are pivotallyconnected with the 'frame in a manner"which will b'e presentlydescribed. The rem: portion of the seat is connected, by links. orchains, 7, wit-h the swinging edge of the. upper or front bed- .sectioILThe back B is equipped with astructure is in sofa form catch-member 8which is rigidly secured thereto;'and a loop, or handle, 9 is provided,by means of which the back may be swung forward to enable it to belockingly engaged with the rear portion of the seat. The rear portion ofthe seat is equipped with a movable catch 10 which is pivotallysupported at l1, and which maybe released by means of a loop, or handle,12. When the structlu'e is in the sofa. form, the catches are inengagement with each other, and release may be effected by n'ioving thecatch l() through the/,medium of the loop 12. The particular form ofmeans for locking the seat and back together is of 'no importance, andno claim to a specific device for sueh purpose is made herein.

The folding bed I) comprises an upper o1' front section 13; a lower orrear section 14; and an intermediate section 15. The inter- .mediatesection is securely fastened by bolts 16 to the arms of the truss E. Theintermediate section comprises end-members; and the front and rearsections comprise substantially U-shaped members having the eX tremitiesof their arms connected, respectively, by pivots 17 and 18, with theextremities of the end-1nembers of the intermediate section 15. AThefolding bed-frame, or mattress-frame, has attached thereto the flexiblebed-bottom, or wire mattress, 19.

The truss E upon which the intermediate section 15 of the bed-fra1ne ismounted, comprises, in the form shown, a longitudinally disposedchannel-bar 2O having pivot-studs 21 projecting from the ends thereof;and upwardly extending arms 22 which may be formed of angle-bars,secured. at rightangles to the channel-bar 20, the pivots 21 `projectingbeyond the uprights 22. The arms 22 are connected with the longitudinalmember 20 by braces 23. The ends of the arms 22 are provided withperforations 24 which receive the pivotal bolts 16 which serve toconnect the intermediate bed-section with the truss. The end-standards-1 of -the main frame are equipped with pivot-plates 25 which areloca-ted at the front portions of said standards a short distance abovethe lower ends of the standards. 4The plates 25 are of Z-form, and -haveperforations 26 adapted to receive the pivots 21 of the truss E, andperforations 27 adapted to receive pivotal rivets 28 which serve toconnect the links (5 with the plates 25. The Webs 29 of the Z-formplates 25 are disposed horizon tally and aHord ledges upon which thelinks '6 bear When the bed is unfolded and the links 6 are in thehorizontal position shown in Fig. 1. The channel-bar 20 of the truss Ehas secured to it a front piece, or molding, 30 which lies in a verticalplane when the and which swings to a horizontal ,plane when thestructure is lin bed form. The space between the front portion of theseat and the front piece 30 is spanned by fabric 31 which conceals theinterior structure. l

Pivotally connected with the end-members of t-he front bed-section 13are folding legs 32 which have extensions above their pivots which arepivotally connected with links 33 whose opposite ends are connected, bypivots 34, with the intermediate bed-section.

The links F are joined by pivots 35 to the rear pori ions of theend-1ne1nbers of the bed* section I4, and the links have extensions 3Gwith which are pivotally connected links 37 whose other ends areconnected, by pivots 38, with the intermediate bed-section. The lowerends of the links,. or legs, 'F are equipped with cam-studs 39 whichmove in inclined guides 40 with which the end-standards of the mainframe are equipped on their inner surfaces. Springs 41 connect the legsF with the rear portion of the frame-section 14.

rI`he operation will be readily understood from the foregoing detaileddescription. The bed is usually made up before converting the structuret-o sofa form, the beddinff, which includes the mattress proper, thebedlinen and covers, being secured to the mattress-frame, or bed-frame,so as to fold therewith.' In converting to sofa form, the seat is swungfrom the position shown in Fig. 1 to the position shown in Fig. 3. Inthis operation, the links 4 and 6 assume the position shown in Fig. 3,and the bed-frame is folded to the position shown in Fig. 3. In the sameoperation, the truss E turns upon the trunnions, or pivots, 21, thuscarrying the pivots 1G downwardly and rear'- wardly. At the same timethe links, or legs, F swing rearwardly about the studs 39, while thestuds 39 also slide in the guides 40. In the sofa form, the intermediatebed-seo tion 15 assumes a vertical position and the arms 22 of the trussE assume a horizontal position. After the seat has been swung to thenormal position for use as a seat, the lower portion of the back isswung forwardly through the medium of the loop 9, and the back isloekingly engaged with the catch with which the seat is equipped.

In converting from sofa form to bed form, the loop 12 is employed tolift the rear'portion of the seat, the initial lift serving to releasethe back, which swings to the vertical position shown in Fig'l. -In theoperation of swinging the seat to the position shown in Fig. 1, thelinks 4 and 6 Iare brought into substantial alinement, .and the links Grest upon `the ledges 29 ofthe pivot members i' 25. The links 4 areequipped with stops 42 which engage the projecting ends of the linksl 6,so that the edge of the seat which lies adjacent to the frame in theinverted position of the seat will be supported` through the medium ofthe links 4 vand 6. The opposite edge ofv the seat is supported .ist

. legs through the medium of the chains-7. In the f loperation ofswinging the seat to the inverted position, the bed is unfolded throughthey medium of the chains 7, the truss E swinging upon its pivots sothat its arms assume an .upright position and elevate the intermediatesection of the bed. In the unfolding operation, the front legs 32 andrear F are swung to thev upright position through the medium of, thelinks 33 and 37, respectively. f

The foregoing detailed description has been given for clearness ofunderstanding only, and no undue limitation should be understoodtherefrom. Hence,- the appended claims should be construed as broadly aspermissible in view of the prior art.
